May 20, 1947. F. E. DAVIS I FLYING GOILER Fi1ed Dec. 6, 1944 4 Sheets-Shet 2" atented ay 20, 1947 FLYING COILER' Floyd E. Davis, Gary, Ind. Application December 6, 1944, Serial No. 566,929 7 1 This invention relates to flying coilers for-rods and the like. In the manufacture of rods, bars and other similar products it is often necessary to form them into coils. In many instances the coils are formed as the rod leaves the rolling mill or the hot bed, while traveling at a relatively high rate of speed. At present two types of coilers are in general use. For catching the bar on the fly, ther is a spike type coiler which is operated with a stationary face plate opposite a rotating spiked face plate. This type of coiler is defective in that there is an excessive breakage of spikes and the bars are damaged by being rubbed against the stationary face plate. The other type of coiler in general use is the collapsible drum type which must be stopped and hand fed for each coil. These stops cause delays and interfere with steady production.

It is an object of this invention to provide a coiler which has positive means for catching'and Another object is to provide a coiler which will wrap the material uniformly about its drum.

A further object is to provide a coiler which will maintain the shape of the coil upon discharge therefrom.

These and other objects will be more apparent after referring to the attached drawings, in which:

Fig. 1 is a cross-sectional elevation of the coiler in discharge position, the head end of the reel being shown on a line through the keyed-connection of the drum;

Fig. 2 is an elevation partly in cross-section, showing the coiler in catching position;

Fig. 3 is a view similar to Fig. 2, but showing the coiler in gripping position;

Fig. 4.is an end view of the reel, partly in crosssection, showing a rod in position to be gripped;

Fig. 5 is a section taken on the line V--V of Fig.

Figs. 6 and '7 are views showing the position of the serrations as they grip the material to be coiled.

Referring more particularly to the drawings, the reference numeral 2 indicates the reel of a coiler. The reel is composed of two identical halves which face each other and rotate together. Each half includes a face plate 4, a collapsible drum 6 having a plurality of segments 8, and a stripper plate I8. The spider l2,of the stripper plate is mounted on a tapered hub M which cooperates with corresponding tapers IS on thedrum segments 8. The jaws of the drum seg- 25 claims. (01. 242-81) holding the leading end of a rod on the fly and which will not damage the surface thereof ments have 'zigzaggripping teeth or serrations I 8 on the outer edges thereof for gripping the rod 28 therebetween and preventing it from working down between the jaws as it is coiled around the drum. The shape of the serrations [8 may be varied to-grip a bar or other shape of material as shown in Fig. 'I. The drum segments 8 overlap each other at 22 as shown in Fig. 5, to prevent the material from catching and .wedging therebetween and are keyed to the face plates by dovetailed keys 23.

The head end of the reel is mounted on the stationary bed 24 and the tail end on carriage 26 which slides on the ways 28 on bed 24. If desired, the head end of the reel may be similarly mounted on a movable carriage so that either or both drums maybe moved toward and away from the other. The face plate 4 of the head end of the coiler is attached to a hollow spindle shaft 30 which is mounted for rotation in bearings 32. The

face plate 4 of the tail end is attached to a hollow spindle shaft 34 which is mounted for rotation in bearing 36. The two halves of the reel are syn chronously driven by means of a motor 38 through motor pinion 48 in mesh with a gear 42 mounted on drive shaft 44 which is mounted for rotation on the stationary bed 24. Mounted on drive shaft 44 is a pinion 46 which drives the spindle shaft 30 by means of a gear 48 mounted thereon. On the tail end of shaft 44 is mounted a pinion 58 which drives the spindle shaft 34 by means of a gear 52 mounted thereon. The pinion 50 has a wide face so that it will be in mesh with the gear 52 regardless of the position of carriage 26. Extending through hollow shaft 38 and supporting the stripper plate III of the head end is a shaft 54 which is moved in relation to the face plate 4 by means of a lever 56 connected to the piston rod 58 which is actuated by means of pressure applied to the cylinder 60. In like manner the stripper plate ID of the tail end is moved by means of shaft 62 mounted within shaft 34 andwhich is attached to lever 64 connected to the piston rod 66 which is actuated by means of pressure applied to cylinder 68.

Connected to the carriage 26 is a piston rod 18 which i-s'actuated by pressure applied to the cylinder 12. On the head end of the piston rod 18 8i. The other arm of the bell; crank lever is connected to a link 90 which rotates a cam 92. Spring 94 is connected to the free end of the link Ell. Connected to the adjustment nut 16 is one end of a toggle 96, the other end being connected to the bracket St. A spring 98 has one end connected to the toggle 96 and the: other connected to lever 90.

The operation of the device is as follows: With the coiler in the position shown in Fig. l, the motor 38 is started, thus causing the two face plates 4 to rotate in synchronism; Pressure is then admitted to the outer ends of cylinders 60 and 68, thus drawing the stripper plates l back against the face plates 4 as shown in Fig. 2. Pressure is admitted to the tail end of cylinder 12 which moves the carriage 26 a distance of stroke Hill where the nut 76 acts as a stop for nut 14 to establish'the gap H12 between the gripping teeth I8. (See Fig. 2.) This sets the collar in the catching position. By adjusting the position of nut 18 the width of gap Hi2 may be varied.

. As the material to be coiled approaches the coiler,

prising opposed collapsible drums, means for rotating the drums in synchronism, means for moving at least one of said drums toward and away from the other, serrations on the edge of each it strikes a flag I94 and actuates it to make contact with the contactor Hi6, thus closing the circuit to the solenoid causing it to rotate the bell crank lever 86clockwise. This pulls the lever 98 to the left to rotate the cam 92 causing it to break the toggle 96 as shown in Fig. '3. With pressure still applied to the tail end of cylinder 12 the breaking of the toggle causes the carriage 26 to be moved over the additional stroke "18 (See Figs. 1 and 2) to establish the gap HG (Fig. 6), thus gripping the leading end of the rod between the serrations l8. It will be understood that suificient time elapses between the striking of the flag Illa by the rod and the movement of the carriage 26 to permit the rod to enter between the serrations l8. E'he gap HI! and its related gap H2 are adjustable by nut 15 to limit the deformation of the material being coiled and to enable material of different thicknesses or widths to be gripped.

The modified members in Figure 7 are indicated by the reference numerals 20' HD' and H2.

When the coil is completed, the contact M8 is opened, thus opening the solenoid circuit. The motor 38 is stopped and pressure admitted to the head end of cylinder 12 to force the carriage to the right, thus spreading the face plates s. With release of the pressure on nut 18, the springs 94 and 88 return the toggle 8% to the position shown in Fig. 1. Pressure is admitted to the inner ends of cylinders 69 and 68 to push the stripper plates out into the position shown in F. i.' As

the stripper plates are pushed out, the tapered "Since the innerconvolutions of the coil all have the same diameter, the coil is easily fitted to an uncoiler for subsequent processing.
